The compound naci is an example of a /an.. (a)covalent bond (b)ionic bond (c) metallic bond (d) none of the above

The answer should be B, ionic bond.

Ionic bond is the bonding between a metal and a non-metal. While covalent bond is the bond between non-metals, and metallic bond is the bond between metals.

Since Na, sodium, is a metal, and Cl, chlorine, is a non-metal, the bond formed between them is an ionic bond. Sodium gives up an electron to chlorine inside this bonding.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
